Thomas Vox replacement transistors

[R.G.]

How many numbers are you missing? Listable or too many?

I compared the Thomas field replacement list and Organ Service list to the list of part numbers I gleaned from my service schemos, and I'm down to three part numbers which don't have a recommended commercial replacement in either. These are:

86-4043-2 (early Essex Bass V-4, V104)
86-4050-2 (11x1 models, reverb input device)
86-4051-2 (11x3 models, reverb section)

I can pick my own replacements for these, but it would be nice to see what Thomas Organ thought.

Do you think the Thomas Organ transistor reference guide would have it ? Found it for $5 and would be nothing to get. Looked for the sheet but still couldn't find it, sorry bout that. Could be in my storage warehouse where some old wahs are .

I didn't know there was one of those, but yes, I think it might help. I'd love to see scans or buy it from you.

Should have it in a few days but will shoot you a copy. Was hoping they would send it over the net but it's a hard copy and says Thomas-Vox replacement transistor reference so we'll see.

Quick update: I put more info in the page: what model numbers use what Thomas Organ transistors, tuning and rebiasing descriptions and example schemos, and more info on commercial replacements I scratched out.
